title: [Immediate and late prognosis in patients with unstable angina under medical treatment].
abstract: The study was undertaken to examine 221 patients with unstable angina (UA) in the acute period and repeatedly on average of 5.3 years later. Myocardial infarction and sudden coronary death were regarded as unfavorable outcomes of UA. Out of all the patients included into the study, 33 (15%) developed myocardial infarction on days 2-28 of hospital stay, which resulted in death in 7 patients; 6 more patients died suddenly. The hospital mortality rate was 5.8%. Of 175 patients discharged from the unit, 31 developed myocardial infarction in the late period, 1 case ended with a fatal outcome, sudden coronary death was observed in 32 cases. The mortality rates by years were the following: 10.2% within the first year, 17.4% for 3 years, and 28.2% for 5 years. The choice of a complex of initial signs mostly significant for defining the risk for complications with the use of Cox's model of proportional risks indicated that the outcome of UA was affected by the following significant factors: 1) ST segment depression in the leads V4-V6; 2) duration of aggravated condition; 3) duration of coronary heart disease; 4) the number of resting anginal episodes; 5) a patient's fitness on his admission to hospital; 6) a history of arterial hypertension; 7) negative T waves in the leads V4-V5.
